Hello,
I have an image of separated shapes and Im trying to get thier centroids.
The image is binary-like image means it fills with zeros and any shape is fills with numbers.
Say there are 10 shapes in the image, every shape has its number from 1 to 10 and that is the value in the image.. i would like to get 10 centroids of the shapes.

Try my Image Segmentation Tutorial. It gives a well commented demo to find the centroids and other things.

In short,
binaryImage = grayImage > 0;
props = regionprops(binaryImage, 'Centroid')
centroidsxy = vertcat(props.Centroid)
